Description
Solar energy is converted to?electrical energy by photo-voltaic (PV) cells.? This energy is stored in batteries during day time for the utilization purpose whenever required. This project is designed to use solar energy for household loads using an inverter.
A?solar inverter, or?PV inverter, converts the?direct current (DC) output of a?photovoltaic?solar panel?into a?utility frequency alternating current?(AC) that can be fed into a commercial electrical?grid or used by a local,?off-line?electrical network.
In this project, the solar energy is stored in the battery from Photo-Voltaic cells. This stored energy of the battery is converted to AC supply of 50Hz frequency using PWM inverter IC with MOSFET gate driver IC to the driver MOSFET bridge and step-up the voltage by a transformer, all in off line network only but not grid tie type.
For demo purposes a battery of SMF type of & .5 AH (not supplied). It is generally used in small UPS) is required to be used as solar cells required would be of very high power type costing very high.
Furthermore, this project can be added with a charge controller with over and under voltage protection and over load protection.
